C630-1车床主轴(图1)系多台阶梯类锻件,过去在750公斤空气锤上二火锻成,最后还要热校直,共需更换八、九套尺寸不同的摔具(图2)。锻件的产量和质量都很低,而劳动强度却很大。现改为在2吨蒸汽锤上,用操作机和固定在砧座上的三套活动摔具(图3)一火锻成。摔具放在摔具框(图4)内,摔具框安装在摔具架(图5)的三个角上的立轴上(图6),能自由 C630-1 lathe spindle (Figure 1) Department of multi-step forgings, 750 kg air hammer in the past on the second fire forging, and finally heat straightening, the total need to replace eight or nine different sizes of wrestling (Figure 2 ). Forgings production and quality are very low, but the labor intensity is great. It is now replaced by a 2-ton steam hammer, with a manipulator and a fixed anvil on the three sets of activities (Figure 3) a fire forging. The wrestler is placed inside the wrestling frame (FIG. 4), the wrestling frame is mounted on the vertical shaft (FIG. 6) on the three corners of the wrestling stand (FIG. 5)
